AbstractA nation-wide perinatal census which included 22,815 deliveries was carried out. The cesarean section rate was 9.6% and the perinatal mortality rate was 13.5/1000. Using a logistic regression analysis the risk factors for cesarean section and for perinatal mortality were ranked. Breech presentation and one uterine scar were found to be the most important risk factors for cesarean section and breech presentation, maternal disease and multiple pregnancy for perinatal mortality. Low birth weight rate was 6.9% with nonsignificant differences between the various ethnic groups. The national cesarean section rate in breech presentation was 57.8%. It was performed mainly at the extremes of birth weight. From those with one previous cesarean section 55.1% delivered vaginally and 44.9% abdominally. The chance for vaginal delivery is higher (67.2%) providing the woman had delivered vaginally in the past. Comparison between primiparae and multiparae showed that preeclampsia, hypertension and diabetes mellitus were all significantly more frequent among older parturients and among primiparae.
